Geothermal energy

Geothermal Energy is one of the most reliable sustainable and renewable energy source available today. The knowledge on utilization of geothermal energy for both electrical production as well as district heating, and other direct usage has been building up rapidly in Iceland and abroad for the last decades. 

EFLA is one of the world's few engineering consulting firms with decades of experience in harnessing this rapidly emerging but technologically demanding energy source.


We offer advice on business modelling and planning, and assist our clients with financing geothermal projects. In addition, we understand the close relationship of successful geothermal projects and characterization of the geothermal resource. Therefore, we place special emphasis on the exploration of geothermal resources as part of geothermal projects. 

EFLA is experienced in feasibility studies and cost estimation for geothermal power plants as well as direct usages of the geothermal energy.
